Abstract

The embodiment of the invention relates to the field of micro projector engines, and discloses a double-reflection type micro projection optical engine which is compact in layout, small in size and convenient to carry, and comprises a light source, a DMD chip, and a collimation light combination module, a fly-eye lens, a reflector, a curved light prism, a prism combination and a projection lens which are sequentially arranged in the light emitting direction of the light source, according to the invention, the light path direction of the illumination light is adjusted through the reflector and the curved light prism, and the light path direction of the image light is adjusted through the light path design of the combination of the DMD chip and the prism, so that the long and short sides of the projection area and the long and short sides of the projection light machine are kept consistent in direction after the image after the image light is emitted is projected and imaged.

Description

technical field [0001] Embodiments of the present invention relate to the field of micro-projector engines, in particular to a double-reflection micro-projection optical engine. Background technique [0002] Projectors are very popular among users because they can project images with a wide field of vision. With the development of electronic technology and multimedia technology, users have higher and higher requirements for projectors. While the projection effect of projectors is continuously optimized, it is also developing towards miniaturization and thinner, making users easy to carry and enjoy large-scale video anytime, anywhere. screen visual effects. [0003] In the process of implementing the embodiments of the present invention, the inventors found that there are at least the following problems in the above related technologies: the existing projectors are large in size and inconvenient for users to carry; The directions are usually inconsistent, which will limit t...
